Abstract: A cushioning wrap material includes an elongate layer of expanded sheet material comprising an array of openings, and an elongate layer of interleaf material secured to the layer of expanded sheet material in face-to-face relationship. The expanded sheet material is expanded in length and thickness, and the layer of interleaf material may have a width equal to or less than a width of the layer of expanded sheet material. Typically, the layer of interleaf material is secured to the layer of expanded sheet material such that respective longitudinal centerlines of each layer are substantially aligned. The layer of expanded sheet material and layer of interleaf material secured thereto are then wound into a roll. Typically, each layer is at least thirty feet in length.

Abstract: A control system for a lift axle suspension wherein two or more axle suspensions are mounted on a vehicle frame and a liftable axle is automatically raised or lowered depending on the load on another of the axle or axles. An override to the automatic lift system is provided when the vehicle is fully loaded to lift a liftable axle selectively for a limited, relatively short period of time to assist in maneuvering the vehicle. The control system detects the load on one axle and automatically raises the second axle to the raised position when the load on the first axle is below a first predetermined value and automatically lowers the second axle to the lower position when the lower load on the first axle is above a predetermined value which is greater than the first predetermined value. A delay is provided in the operation of the control system to lower the second axle upon the detection of the load on the first axle to compensate for road bumps.
